Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031866, here are decompositions:

29 + 1031837 = 1031866
53 + 1031813 = 1031866
107 + 1031759 = 1031866
113 + 1031753 = 1031866
137 + 1031729 = 1031866
149 + 1031717 = 1031866
197 + 1031669 = 1031866
233 + 1031633 = 1031866

Showing the first eight; more decompositions exist.
